v0.9.16

BREAKING CHANGES

• due to 5ffcd56 - return JSON from template endpoints (PR #247 by @IT-coder-Yy):

  Template success responses now use application/json and Protobuf JSON field names. Callers must decode JSON instead of Protobuf binary.

  • fix(client)!: decode JSON template responses
    Request JSON and parse template responses through the shared Protobuf JSON schema. Update HTTP fixtures and editor regressions while retaining binary save requests.
    The template client requires the server version that returns JSON success responses.
  • docs(server): describe template JSON response contracts
  • docs(client): clarify template request and response formats
  • docs(api): document the template JSON migration
  • fix(server): preserve legacy template response decoding
  • fix(client): tolerate evolving template response formats
  • docs(api): explain template response compatibility

• due to 508671b - map keywords by ID and retry invalid outputs (PR #248 by @muyuzhong):

  ASR-backed keyword extraction requires a model endpoint
  that supports strict JSON Schema with minItems/maxItems constraints.
  Unsupported endpoints fail instead of falling back to JSON mode.

  • docs: shorten segmentation collaboration notes
  • fix(segmentation): use DeepSeek-compatible JSON output
  • fix(segmentation): map keywords by segment ID
  • fix(segmentation): bound correction attempts and timeouts
  • fix(segmentation): cap requests and share a time budget
  • fix(segmentation): redact detailed logs and use debug
  • fix(segmentation): allow thirty seconds per model request
  • fix(segmentation): address review feedback on correction retries
  • Read missing or null choices, message, and content as an empty reply,
    so boundary and keyword stages retry instead of raising AttributeError.
  • Do not send an empty assistant turn when correcting an empty reply;
    append only the correction message.
  • Use a non-empty title_keyword placeholder in the keyword example.
  • Let the default test stub accept title input, and cover corrected
    boundaries and title keywords after a failed first attempt.

  • docs(segmentation): condense segmentation notes
    Shorten the segmentation sections of AGENTS.md and server/README.md and
    state that invalid per-segment keywords are emptied without correction.

v0.9.11

BREAKING CHANGES

• due to 815ea71 - remove local templates and keep templates cloud-only (PR #223 by @YUZHEthefool):

  desktop local templates are no longer shown or edited.
  The old data/template/templates.json and the $client.template_path
  setting stay on disk untouched; templates still needed must be
  recreated as cloud templates.
  Refs #209

  • docs: drop remaining local template library wording
    The cloud-only change left sentences that still described local templates:
    README and README.zh said local and cloud templates do not sync and that
    both libraries share the same save checks, client/README said both use the
    same font catalog and validation rules, and AGENTS.md still described local
    detail reads, local list summaries and a local JSON corruption error.
    Describe saving, reading and listing for the single cloud library only.
  • docs(proto): describe template messages as cloud-only
    The header comment still said the messages are shared by the cloud API and
    local save requests. The local save path and its Rust prost output are gone,
    so reword it and carry the comment into the generated TypeScript header
    (regenerated with buf; the Python outputs are unchanged).
  • test(client): cover reopening a legacy local template position
    An update recovery position saved by an older client carries an environment
    field and may point at a local template. The editor now ignores the field
    and reads the ID from the cloud library; check that a not-found answer shows
    the retry action, drops the stale position, and a retry restores the template.
